T4 Inlet Manifold Turbo Hose - 1.9 Turbo Diesel Engines - (ABL Engines)

This inlet manifold turbo pressure hose is a direct replacement for the charge/boost hose used on VW T4 Transporter 1.9 Turbo Diesel (ABL) engines. It carries pressurised air from the turbo/charge system into the inlet manifold, ensuring the engine receives the correct volume of boosted air under load.

Because this hose operates under boost pressure and high under-bonnet temperatures, the original can weaken over time. Common symptoms of a failing pressure hose include hissing under acceleration, oily misting around joints, reduced power, poor boost response, increased smoke, and limp-feeling performance. Replacing the hose restores a sealed intake tract so the turbo can build and hold pressure properly, improving drivability and protecting the turbo from overspeed caused by leaks.

The hose is formed to the correct shape for the T4 engine bay, helping it sit without kinks and maintain consistent airflow. It’s an ideal replacement when servicing the intake system, chasing boost leaks, or refreshing ageing rubberwork on higher-mileage vans.

Quantity & Fitting Notes

• Sold individually

• Inspect/replace any tired hose clips at the same time (boost leaks are often clamp-related)

• Check connecting pipes and manifold/turbo outlets for corrosion or sharp edges that can cut new hoses

• Clean oil residue from joints before fitting to help the hose seat properly

Related Parts You May Need

• Boost/charge hose clips (recommended to renew)

• Intercooler/charge pipe seals (if fitted on your setup)
